MongoDB and MacPorts (and v8)

In order to upgrade MongoDB to the latest version (using MacPorts), I had to deactivate v8, upgrade MongoDB and activate v8 again:


--->  Configuring mongodb
Error: mongodb cannot be built while v8 is active.
Error: Please deactivate v8 and try again.
Error: You can reactivate v8 again later.
Error: org.macports.configure for port mongodb returned: v8 is active
Please see the log file for port mongodb for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_databases_mongodb/mongodb/main.log
Error: Unable to upgrade port: 1
